Chemical Structure
Description
N-cyclopentyl-4-(2-phenylacetyl)-1H-pyrrole-2-carboxamide (CAS 477870-49-8) is a high-purity analytical reference standard with the molecular formula C18H20N2O2 and a molecular weight of 296.36 g/mol.
N-cyclopentyl-4-(2-phenylacetyl)-1H-pyrrole-2-carboxamide (C18H20N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), N-cyclopentyl-4-(2-phenylacetyl)-1H-pyrrole-2-carboxamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
